This tool presents average farm price
received data, for multiple commodities, in the US
for the period 1960 to present. These historical price series
are often useful for long-range planning. Seven commodities are
included in the tool: corn, soybeans, wheat, barrows and gilts,
steers and heifers, calves and milk. It is important to
note that the prices represent the average price actually received
by farmers, and therefore, may be different from average prices
offered by the market.

The source for the data is the National Agricultural Statistical
Service (NASS) of the US Department of Agriculture ( http://www.nass.usda.gov/index.asp
). Annual average
prices are based on calendar years for all commodities. Seasonal
average prices are computed only for corn, soybeans and wheat
and are based on marketing years (Sep-Aug: corn and soybeans;
Jun-May: wheat.)
